I think you are talking about two problems here. Let's see...
First, it seems that you have some sort of problems with your swap but,
what are those problems exactly?
Some hints:
- With 8 GiB of RAM you can (almost) safely turn off your swap at all, it
shouldn't be used. You can indeed run this test (→ turn off swap) to see
how your system behaves.
- The kernel will use all of the system resources which are available and
that includes /swap.
Second, you say you can't delete big files (>1 GiB of size) because your
system becomes unmanageable and runs out of memory. This is of course not
normal (even a system with as little as 256 MiB of RAM shouldn't
experience this problem at all).
Some hints:
- How are you deleting the files? You can try with a GUI based
application (e.g., nautillus) and then compare the results using the
command line (rm my_big_file).
- Are you getting any entry for the OOM error at the logs (/var/log/
syslog)?

I'm not completely sure what you mean by this :-?
